Piston Slap: Traversing the World of LED Retrofit Bulbs!

Sajeev,

Your recent Piston Slap on HID lights reminded me of a problem I had with replacing tail lights on my wife’s 2009 Traverse. One of the OEM bulbs burned out, so I decided to replace both brake/tail lights with LEDs.

The LED lights worked great and were brighter than the OEM bulbs, but there was just one problem–the turn signals would blink rapidly, just like they did with the burned out bulb. After I went back and RTFM I learned the rapid blinking or “hyper-flashing” occurs when a bulb is burned out OR the system is drawing little to no current. Since the LEDs use a lot less power, the system thinks the bulb is burned out.

  • MaintenanceCosts Depends on the record of the company developing them. If it’s got a record of prioritizing safety over years of development, I’ll be fine with it, and I’ll expect it to be less risky than typical idiot human drivers. If it’s a “move fast and break sh!t” outfit like Tesla or Uber, no way.
